I have problems with the speed of the video, I had a 50% video and then I set it to% 1000 speed and it did not apply the video, it's something simple because it's just cutting and playing with speed, but it has faults.




I have to close and reopen

In other cases there is no video

Put each clip on different tracks. Then apply the speed effect. That the clip can shrink/extend accordingly. In the top example you put the speed effect with 2 different settings on the same clip so they block each other.
